[0005] 本发明技术方案是,一种提高涤纶纺粘非织造布均匀度的方法,它是在涤纶纺粘非织造布的生产设备的牵伸器入口处,通过一根静电放电棒为熔融纺丝冷却后的纤维施加一定量的正静电荷,正静电荷的施加量应保证纤维在离开牵伸器后因带有同种电荷发生相斥作用,使纤维之间相互分离,减少并丝、丝束及粘连丝的现象,铺成后的网帘均匀,从而提高产品均匀度。 [0005] aspect of the present invention, a method of non-woven spunbond polyester fabric uniformity improved, which is in the inlet drawing polyester spunbond nonwoven fabric production facility, by an electrostatic discharge rod is molten positive electrostatic charge is applied to the fiber after spinning a quantity of cooling, the amount of applied positive electrostatic charge repulsion of the fibers should ensure that with the same type of charge occurs because after leaving the distraction, so that the fibers separated from each other, and to reduce the wire , and adhesion phenomena tow wire, mesh screens after the paved evenly, thereby improving the uniformity of the product.

[0006] 由于大量的静电荷对铺网后的加工程序不利,而且带静电的无纺布容易吸附灰尘,所以在铺网机网帘的末端安装静电消除器,再将加上的正静电荷消除掉。 [0006] Since a large amount of electrostatic charge after the machining program laying unfavorable, and the nonwoven fabric easy to absorb dust electrostatically charged, so that at the end of the installation static eliminator mesh plies lapper, and then coupled with a positive electrostatic charge eliminated.

[0007] —种实施上述方法的静电分丝装置,它是由布置在工作现场以外的可调式静电发生器和安装在牵伸器入口上方IOOmm处的静电放电棒组成,可调式静电发生器和静电放电棒用导线连接;静电放电棒的长度应满足牵伸器的长度。 [0007] - two electrostatic sub-wire device according to the above method, which is adjustable by the static generator disposed outside the job site and installed at an electrostatic discharge rod IOOmm composed drawing above the inlet, and adjustable electrostatic generator electrostatic discharge is connected with a wire rod; rod length should satisfy ESD length of distraction.

[0008] 上述的可调式静电发生器应输出1-10万伏的高压。 [0008] The electrostatic generator should be adjustable 1-100 000 volt high voltage output.

[0009] 生产时,通过调节静电发生器的电压大小并观察铺网情况,当均匀度达到最佳时,固定该电压,生产一段时间后取样,测量CV值进行比对,再重新调整电压大小,保证整个生产过程的均匀度。 [0009] production, by adjusting the voltage and observing the magnitude of the electrostatic generator laying, when the best uniformity, the voltage is fixed, the sampling period of time after production, the CV values ​​measured for comparison, and then re-adjust the magnitude of the voltage , to ensure uniformity of the entire production process.

[0010] 由于采取本发明的技术方案,解决了长期以来人们渴望解决的涤纶纺粘非织造布的均匀度问题,尤其是对小于每平方100克重的涤纶纺粘非织造布,其优越性更加显得突出。 [0010] As a result of the technical solution of the present invention solves the problem of uniformity has long been a desire to solve spunbonded nonwoven polyester fabric, especially less than 100 grams per square weight of the polyester spunbonded nonwoven fabric, its superiority seem more prominent.
